After going down last time, I’d probably go up this time, so long as the jump wasn’t too big. I think I was best to stick to a large with the last bike given the XL was so much longer (compared to the jump from medium -> large)
At least with a longer frame you don’t have to shove the seat back, especially with a full suss where it’ll sit back into its travel a bit more going uphill, not having the seat over the back helps with seated climbing I reckon
You can often loose the extra unwanted toptube length off of the stem
A long(ish) stemmed, seat back, short top tubed bike I know I don’t get on with too well
With a short toptubed bike, trying to stick a short(ish) stem on, you’ll end up shoving the seat back, which would be okay if you didn’t do a lot of steep/techy climbs I reckon, but I’ve not got on with that sort of setup before
